Question

Write a quadratic function with zeros -1 and 5.

Answer 1

`x^2+4x-5`

Explanation:

Zeros of a quadratic equation are -1 and 5.

Sum of zeros = -1 + 5 = 4

Product of zeros = (-1)(5) = -5

The quadratic equation will be :

`x^2+(\text{sum of zeros})x+\text{product of zeros}\\\\=x^2+4x-5`

So, the required quadratic equation is
`x^2+4x-5`.
